NU'EST W and Gugudan were introduced as the first two guests who will be performing on the show this week. While getting started, the MCs recalled that Kim Se Jung and Mina actually appeared in the first season of 'Sugarman' and were asked how they felt about returning to the show.

Kim Se Jung said, "At that time [first season] we got the win and because we brought the same positive�energy, perhaps we will win again." The Gugudan member also said, "Because it was actually my first variety show last time and I wanted to receive a good energy/luck from Yoo Jae Suk sunbaenim, I asked for his signature on a $100 bill prop. I still carry this in my wallet with me wherever I go. Even now, I only have good memories from 'Sugarman'."
